“…Except for the 4S~/2 -2p~/2 line at 703.6 A, all the M1 lines are tentatively assigned. Their measurement uncertainty is ± 0.2 A, giving a level uncertainty of ±40 cm-1 • The transition array 3p 3 -3p 23d was observed in a tokamak plasma by Sugar et al [1991], who classified seven lines in the range of 131-137 A measured with an uncertainty of ±0.005 A. We quote their levels.…”

Atomic energy levels of germanium have been compiled for all stages of ionization for which experimentaJ data are available. No data have yet been published for Ge VIII through Ge XIII and Ge XXXII. Very accurate calculated values are compiled for Ge XXXI and XXXII. Experimental g-factors and leading percentages from calculated eigenvectors of levels are given. A value for the ionzation energy, either experimental when available or theoretical, is included for the neutral atom and each ion.

“…50 background images were collected before and after every 2000 images. The energy axis was obtained by measuring a copper target emission spectrum and calibrating it using tabulated data for highly ionized atomic copper lines [8]. This results in an absolute energy calibration of 0.2eV [9].…”

We present advanced instrumentation for the investigation of thin organic films offered by a laboratory X-ray absorption fine structure (XAFS) spectrometer for the soft X-ray range. The transmission spectrometer is based on a laser-produced plasma source in combination with a twin-arm reflection zone plate spectrometer. The efficiency and stability of the spectrometer allow for single shot measurements within 500 ps with a resolving power of E/ΔE ~ 900 in a range between 200 eV and 1300 eV. Through the implementation of an optical pump beam, also transient absorption measurements can be performed. The merits of the spectrometer are demonstrated through the investigation of poly[(9,9-dioctylfluorenyl-2,7-diyl)-alt-co-(1,4-benzo-{2,1',3}-thiadiazole)] (F8BT), a poly-fluorene copolymer. Transient optical pump soft X-ray probe spectroscopy with 500 ps time resolution detects changes in the C K edge spectrum which can be attributed to the lowest unoccupied molecular orbitals of the molecules in the benzothiadiazole unit.

“…The basic spectroscopy of the aforementioned S-like HCIs have been investigated before for their extensive usages in the identification and interpretation of the emission lines in the astrophysics, fusion reactors, plasma diagnostics, etc. [12][13][14][15][16]. However, most of these studies are concentrated on the allowed transitions, since their optical signals can be observed easily.…”

Selective highly charged ions as the prospective optical clock candidates with quality factors larger than $10^{15}$

We propose here a few selective highly charged ions (HCIs), namely Ni 12+ and Cu 13+ , Pd 12+ and Ag 13+ , that not only promise to be very high accurate optical clocks below 10 −19 uncertainties, but also offer quality factors larger than 10 15 and yet possess simple atomic structures for the experimental set-up. Moreover, these ions have strong optical magnetic-dipole (M1) transitions than the previously proposed HCI clocks. They can be used for the cooling and detection techniques. To demonstrate the projected fractional uncertainties below 10 −19 level, we have estimated the typical orders of magnitudes due to many of the conventional systematics manifested in an atomic clock experiment, such as Zeeman, Stark, black-body radiation, and electric quadrupole shifts, by performing calculations of the relevant atomic properties.
